Prepare Not The Same As Preview


Recommended Posts

Posted (edited) · Prepare Not The Same As Preview

I made a little mountain and base plate part for a project im working on, and when I put the STL in prepare, it looks normal. However, when I slice and preview, it fills in the through hole in the mountain, but only in certain spots. Anyone have any ideas?


Here is the prepare screen after I import the part:



Here is the preview layer 21:

Here is preview layer 101:



Here is preview layer 171

    What cad software did you use?


    Well your model has some problems.  Someone had this very issue in the last 2 weeks and solved it by playing with the mesh options.  Go to the mesh options and click the gear and make them all visible.  I think he removed "overlapping volumes" (unchecked)?  Alternatively you can fix the problems in cad or you can put this through the web based netfabb repair service which is free but you have to create an account.
